If you recently received a data breach notification letter from Quantum Health, Inc., it means your personal information may have been compromised. The company, a healthcare navigation and care coordination provider, filed a report with the Washington Attorney General's office on August 14, 2026, concerning a security incident. These letters are formal acknowledgments that your data was involved.

According to the filing, the exposed information includes highly sensitive details such as your Full Name, Date of Birth, Social Security Number, and Mailing Address. Critically, health-related identifiers like your Health Insurance ID Number, Medical Record Number, Diagnosis and Treatment Information, Prescription Information, and Provider and Treatment Dates were also impacted. Your Phone Number was additionally among the compromised data categories.

The exposure of this combination of personal and health data carries substantial risks, particularly concerning medical identity theft. This type of fraud can lead to false claims appearing on your medical records, impacting your future care, and causing incorrect bills. Beyond medical concerns, the compromise of your Social Security Number and Date of Birth can open doors to long-term financial identity theft and account takeovers.

Upon receiving such a notification, it's prudent to review your explanation of benefits (EOB) statements and credit reports carefully for any suspicious activity. Consider placing a fraud alert or security freeze on your credit files to prevent unauthorized accounts from being opened. Prompt action can help mitigate potential harm from the exposed information.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Check for medical identity theft

    Review the Explanation of Benefits statements from your health insurer for services or claims you never received, which can signal misuse of your medical identity.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
